What's net zero is the line voltage. The issue is partly spinning
mass, but more important is gross gigawatts available on bad
afternoons.

Another time bomb is that (cheap) solar panels and inverters and
batteries don't last as long as is assumed in payback calculations. In
10 or 15 years there will be an enormous disposal problem. And lots of
leaky roofs.

Yep. And given the likely end of the mandates and subsidies,
replacement may prove expensive, making the business case less
attractive.

I remember not too long ago when the climate-change deniers were
claiming renewables could never be a significant part of a country's
energy profile but I guess when they find out Spain was running 73% one
afternoon they have to change their argument, lol.

Better question is will the fission nuclear industry ever give up trying
to push their obsolete pointless technology that has been nothing but
broken promises for 75 years. It's over give up, already.

France will happily sell power to Germany and Spain for maybe 50 cents

I should add that the WSJ is focused on purely financial issues,
specifically where to invest, covering both equities (which stocks to
buy, which to sell) and municipal bonds (loans made to governments to
purchase such thing as bridges, roads, and power plants or
facilities).

The Financial world does not care about technical details per se, they
care that the loans will be repaid. Muni Bond Analysts consider the
engineering as a way to assess the likely scale and practicality.
Whereupon they encounter the big calculator issue - is the entity
large enough to be plausible to accomplish what they claim?

I learned about the financial world by marrying into it - my wife was
a Muni bond portfolio manager. I read some of her tutorials, and was
stunned to learn that while the stock market got all the news media
attention, the Muni market was in fact ten times larger.

Some people enjoy working with money. There are even people who like
being accountants. Electronics is much more fun to me.
Think how much more fun you could have if you actually understood what you were doing.
